Answer:

There is a certain temperature at which an enzyme's catalytic activity is at its greatest which is 37.5 oC

Enzymes are still proteins, and as with all proteins, temperatures above 104 degrees Fahrenheit, 40 degrees Celsius, will start to break them down.

Explanation:

The  temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius).There are also enzymes that work well at lower and higher temperatures.

Answer:

The correct answer is - Behavioral isolation.

Explanation:

In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.

It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.

Answer:

Minerals being deposited as water drips.

Explanation:

Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.

power =F× velocity

=F×d/t=500×4/5=400 watt

Answer:

Long tail and narrow head.

Explanation:

A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.

Answer:

The correct answer is - 25% chances of having puppies with spotty fur.

Explanation:

In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:

Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive

Punnett square:

      S       s

S   SS     Ss

s     Ss     ss

By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.

Answer:

Changes from flooded to drained conditions in soils stimulate changes from aquatic to terrestrial vegetation and decrease the algal contribution to total primary production. Drainage of organic soils then has the effect of removing a source of net primary production (algae) and carbon sequestration

Answer:

Isotopes

Explanation:

If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes. Two terms we use to identify nuclides (isotopes) are atomic number and mass number.

Answer:

One cell divides into two in a process called mitosis. Mitosis produces two genetically identical “daughter” cells from a single parent cell. Another type of cell division, meiosis, creates four daughter cells that are genetically distinct from one another and from the original parent cell. Only a few special cells can perform meiosis: those that will become eggs in females and sperm in males

The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.

Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Explanation:

 The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.

Answer:

1. Increases

2. Decreases

3. Increases

4. Decreases

5. Increases

6. Increases

Explanation:

Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.
